The last of the old time war monitors, five in number, have been condemned by a naval board of survey and the Navy Department will shortly sell them to the highest bidders. The vessels are the Canonicus, Jason [ex-Sangamon], Lehigh, Montauk and Nahant. They are at the League Island Navy Yard. They will probably be bought by junk dealers and broken up for the iron contained in them.
